Title: Optical head
Inventor: MAEDA MIYOZO
IPC: G11B7/135
Filed: 1986-09-05
Abstract: PURPOSE:To raise the power of an erasure optical beam, to use a phase change rewriting medium at a high speed and to improve an erasure efficiency by employing plural laser diodes as an erasure optical beam generation source. CONSTITUTION:An optical beam 2 from a recording/reproducing laser diode 1 is projected on an optical disk 8 rotated by a motor 7 through a collimate lens 3, a cylindrical correction lens 4, a polarized beam splitter 5 and an objective lens 6. By casting a circular optical spot in the prescribed position of the medium of the disk 8, recording and reproducing are made. In a step to erase information, an optical beam from another erasure laser diode 9 is projected on the optical disk 8 as an elliptical optical spot through a collimate lens 11, the objective lens 6, and the like, thereby erasing information. A phase change medium is provided with an erasing/recording optical beam in one head, whereby an overwrite to erase and write information by one rotation is attainable.

Title: Fault monitor device
Inventor: SHIYUDOU TAKEO
IPC: H04L12/26
Filed: 1983-11-08
Abstract: PURPOSE:To use the fault information with high efficiency without scanning the fault input information at all times by using the fault data of a fault monitor controller on each line of a transmission system containing plural controllers as the input data of a maintenance monitor controller. CONSTITUTION:The fault input information Fn is supplied to a fault input table D1 of a common memory CM in a station STN1 of a transmission system TL from an input/output device 101. A fault monitor controller PC1 on each line always scans the information Fn and writes a new fault if occurs to a fault holding table HL corresponding to the table D1. At the same time, a signal PFn is produced with the new fault and then set to an interruption table PF. The signal PFn applies an interruption signal PF'n to the controller PC, and a fault program is turned on in response to a fault group HLX to perform the fault processing. It is avoided that the controller PC always scans the information Fn. This reduces the load of the PC.

Filed: 1982-11-26
Abstract: PURPOSE:To enable to effectively detect the malfunction of a speed feedback signal by detecting the rotating speed of a motor on the basis of measured terminal voltage of the motor, the armature circuit current of the motor and the magnetic flux of the poles of the motor and comparing them with a speed feedback signal. CONSTITUTION:Values measured by a motor field current detector 5, a motor armature current detector 6 and a motor terminal voltage detector 7 are inputted to an operational amplifier 8, which calculates the rotating speed N as the approximate value of the actual rotating speed. An operational amplifier 9 obtains the difference between or ratio of the value of the rotating speed N calculated by the amplifier 8 and the speed feedback signal 10', and inputs it to a comparator 12 through an absolute value circuit 11. The comparator 12 outputs a malfunction detection signal 12-c when the rotating speed difference 12-a calculated by the amplifier 9 becomes the reference value 12-b or higher.

Inventor: SHIMAZAKI YUICHI
IPC: H02K7/18
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To control power generation and generating voltage optimally while enhancing the efficiency and reducing the size and weight by providing means for displacing any one of permanent magnet or armature in the axial direction of relative rotation. SOLUTION: A lever 106 coupled with the plunger 104 of an axial displacement mechanism 100 has free end is installed into a disc 108 through a fulcrum 109. When a solenoid 102 is excited, the plunger 104 is shifted to the right and the free end of lever 106 is displaced to the left thus shifting a stator coil 82 to the left. When the stator coil 82 is located at a position shown by a solid line, flux density interlinking the stator coil 82 is maximized thus maximizing power generation. When it is located at the leftmost position shown by a phantom line, the flux density is minimized thus minimizing power generation. Since the plunger 104 is urged leftward by a spring 110, the stator coil 82 is urged in the direction right for maximizing power generation.

Abstract: PURPOSE:To minimize the recording area of a pilot signal and to improve the S/N ratio by arranging pilot signals of three frequencies dispersively in the lengthwise and vertical directions of tracks in relation to the deviation in arrangement between adjacent tracks at track end parts. CONSTITUTION:A pilot signal generating circuit 19 generates pilot signals f0-f2 of three frequencies having relations f1=f0+fa and f2=f0+2fa. The pilot signal f0 is selected only in a period of pulse width tau with a pulse E from a delay multivibrator circuit 11. Further, the pilot signals are outputted in the order of f1, f0, and f2 when the pulse C from a pulse generating circuit 9 is at H, or in the order of f2, f0, and f1 when at L alternately. The signals f1 and f2 are recorded within the time corresponding to the deviation tau in arrangement and the f0 is recorded successively. Then, they are switched by an unshown video signal processing circuit with the pulse H from a latch circuit 14 to output one continuous reproduced video signal. None of reproduced pilot signals is mixed with this reproduced video signal and the S/N ratio is improved.
